Dose any 1 else have problems with iMessage since IOS 7 came out?

I'm just wondering is this happing to any 1 else or is it just my phone. Ever since I got IOS 7 my iMessage won't work when I try to send a message it is really slow and then when it full loads it doesn't send is this happing to any 1 else. Oh and as well when I got my iPhone 5 my personal hotspot is faulty

Yes my friend has this problem, I don't at the moment but she says it is very annoying!

Yes this happens to everyone apple says their trying to fix it for now go to setting messages and turn I message off it will sent texts not iMessages wen a new update comes out turn iMessage on
